Si value es positivo y toBase es 2, 8 o 16, la cadena devuelta usa la representación de signo y magnitud.If value is positive and toBase is 2, 8, or 16, the returned string uses sign-and-magnitude representation. Si value es negativo y toBase es 2, 8 o 16, la cadena devuelta utiliza la representación del complemento de dos.If value is negative and toBase is 2, 8, or 16, the returned string uses two's complement representation. Esto significa que el bit de orden superior del byte de orden superior (bit 15) se interpreta como el bit de signo.This means that the high-order bit of the high-order byte (bit 15) is interpreted as the sign bit. Si se llama al método ToString(Int16, Int32) para crear una cadena que se convertirá más adelante en un número, se debe llamar a un método correspondiente que asuma una representación numérica similar para realizar la conversión.If the ToString(Int16, Int32) method is called to create a string that will later be converted back to a number, a corresponding method that assumes a similar numeric representation should be called to perform the conversion. Estos métodos incluyen Convert.ToInt16(String, Int32) y Int16.Parse(String, NumberStyles).Such methods include Convert.ToInt16(String, Int32) and Int16.Parse(String, NumberStyles).

Si value es positivo y toBase es 2, 8 o 16, la cadena devuelta usa la representación de signo y magnitud.If value is positive and toBase is 2, 8, or 16, the returned string uses sign-and-magnitude representation. Si value es negativo y toBase es 2, 8 o 16, la cadena devuelta utiliza la representación del complemento de dos.If value is negative and toBase is 2, 8, or 16, the returned string uses two's complement representation. Esto significa que el bit de orden superior del byte de orden superior (bit 31) se interpreta como el bit de signo.This means that the high-order bit of the highest-order byte (bit 31) is interpreted as the sign bit. Si se llama al método ToString(Int32, Int32) para crear una cadena que se convertirá más adelante en un número, se debe llamar a un método correspondiente que asuma una representación numérica similar para realizar la conversión.If the ToString(Int32, Int32) method is called to create a string that will later be converted back to a number, a corresponding method that assumes a similar numeric representation should be called to perform the conversion. Estos métodos incluyen Convert.ToInt32(String, Int32) y Int32.Parse(String, NumberStyles).Such methods include Convert.ToInt32(String, Int32) and Int32.Parse(String, NumberStyles).

Ejemplos

En el ejemplo siguiente se define una clase de NumberFormatInfo personalizada que define su signo negativo como la cadena "~" y su signo positivo como la cadena "!".The following example defines a custom NumberFormatInfo class that defines its negative sign as the string "~" and its positive sign as the string "!". A continuación, llama al método Convert.ToString(SByte, IFormatProvider) para convertir cada elemento de la matriz de bytes con signo en su representación de cadena equivalente.It then calls the Convert.ToString(SByte, IFormatProvider) method to convert each element in signed byte array to its equivalent string representation. La conversión usa la referencia cultural de todos los idiomas, así como el objeto de NumberFormatInfo personalizado.The conversion uses the invariant culture as well as the custom NumberFormatInfo object.

sbyte[] numbers = { SByte.MinValue, -12, 17, SByte.MaxValue};
System.Globalization.NumberFormatInfo nfi = new System.Globalization.NumberFormatInfo();
nfi.NegativeSign = "~";
nfi.PositiveSign = "!";
foreach (sbyte number in numbers)
   Console.WriteLine(Convert.ToString(number, nfi));
// The example displays the following output:
//       ~128
//       ~12
//       17
//       127      
Dim numbers() As SByte = { SByte.MinValue, -12, 17, SByte.MaxValue}
Dim nfi As New System.Globalization.NumberFormatInfo()
nfi.NegativeSign = "~"
nfi.PositiveSign = "!"
For Each number As SByte In numbers

Si value es positivo y toBase no es 10, la cadena devuelta usa la representación de signo y magnitud.If value is positive and toBase is not 10, the returned string uses sign-and-magnitude representation. Si value es negativo y toBase no es 10, la cadena devuelta utiliza la representación del complemento de dos.If value is negative and toBase is not 10, the returned string uses two's complement representation. Esto significa que el bit de orden superior del byte de orden superior (bit 63) se interpreta como el bit de signo.This means that the high-order bit of the highest-order byte (bit 63) is interpreted as the sign bit. Si se llama al método ToString(Int64, Int32) para crear una cadena que se convertirá más adelante en un número, se debe llamar a un método correspondiente que asuma una representación numérica similar para realizar la conversión.If the ToString(Int64, Int32) method is called to create a string that will later be converted back to a number, a corresponding method that assumes a similar numeric representation should be called to perform the conversion. Estos métodos incluyen Convert.ToInt64(String, Int32) y Int64.Parse(String, NumberStyles).Such methods include Convert.ToInt64(String, Int32) and Int64.Parse(String, NumberStyles).

Si el parámetro value implementa la interfaz IConvertible, el método llama a la implementación de IConvertible.ToString(IFormatProvider) de value.If the value parameter implements the IConvertible interface, the method calls the IConvertible.ToString(IFormatProvider) implementation of value. De lo contrario, si el parámetro value implementa la interfaz IFormattable, el método llama a su implementación IFormattable.ToString(String, IFormatProvider).Otherwise, if the value parameter implements the IFormattable interface, the method calls its IFormattable.ToString(String, IFormatProvider) implementation. Si value no implementa ninguna interfaz, el método llama al método ToString() del parámetro value y se omite el parámetro provider.If value implements neither interface, the method calls the value parameter's ToString() method, and the provider parameter is ignored.

El parámetro provider se utiliza si el parámetro value implementa la interfaz IConvertible o IFormattable.The provider parameter is used if the value parameter implements the IConvertible or IFormattable interface. El uso más común del parámetro provider consiste en especificar la información específica de la referencia cultural que se usa en la conversión de value.The most common use of the provider parameter is to specify culture-specific information used in the conversion of value. Por ejemplo, si el parámetro value es un número decimal negativo, el parámetro provider puede proporcionar información específica de la referencia cultural sobre la notación utilizada para el separador decimal y el signo negativo.For example, if the value parameter is a negative decimal number, the provider parameter can supply culture-specific information about the notation used for the negative sign and decimal separator. En el segundo ejemplo de la sección siguiente se muestra un proveedor de formato que no proporciona información de formato dependiente de la referencia cultural.The second example in the next section illustrates a format provider that does not supply culture-sensitive formatting information.

Si toBase no es igual a 10, la cadena devuelta por el método Convert.ToString(Byte, Int32) representa value solo según su magnitud.If toBase does not equal 10, the string that is returned by the Convert.ToString(Byte, Int32) method represents value by its magnitude only. Si se llama al método para crear una cadena que se convertirá más adelante en un número, se debe llamar a un método correspondiente que asuma una representación numérica de solo magnitud para realizar la conversión.If the method is called to create a string that will later be converted back to a number, a corresponding method that assumes a magnitude-only numeric representation should be called to perform the conversion. Estos métodos incluyen Convert.ToByte(String, Int32) o Byte.Parse(String, NumberStyles).Such methods include Convert.ToByte(String, Int32) or Byte.Parse(String, NumberStyles).

Ejemplos

En el ejemplo siguiente se convierte cada elemento de una matriz de bytes sin signo en su representación de cadena equivalente usando las convenciones de formato de las referencias culturales en-US y fr-FR.The following example converts each element in an unsigned byte array to its equivalent string representation using the formatting conventions of the en-US and fr-FR cultures. Dado que el especificador "G" genera de forma predeterminada dígitos decimales en la representación de cadena de un valor de byte, el parámetro provider no afecta al formato de la cadena devuelta.Because the "G" specifier by default outputs only decimal digits in a byte value's string representation, the provider parameter does not affect the formatting of the returned string.

ToString(String)

Devuelve la instancia de la cadena especificada; no se efectúa una conversión real.Returns the specified string instance; no actual conversion is performed.

public:
 static System::String ^ ToString(System::String ^ value);
public static string ToString (string value);
static member ToString : string -> string
Public Shared Function ToString (value As String) As String

Parámetros

value
String

Cadena que se va a devolver.The string to return.

Devoluciones

value se devuelve sin cambios.value is returned unchanged.

Ejemplos

En el ejemplo siguiente se pasa una cadena al método ToString(String) y se llama al método Object.ReferenceEquals para confirmar que el método devuelve la cadena original.The following example passes a string to the ToString(String) method and calls the Object.ReferenceEquals method to confirm that the method returns the original string. En el ejemplo también se llama al método String.IsInterned para asegurarse de que las dos cadenas no son idénticas, ya que se trata de la cadena original.The example also calls the String.IsInterned method to ensure that the two strings are not identical because the original string is interned.
